Is it possible that the Igorina mentioned in Theif Of Time is the same Igorina in Monstrous Regiment? It is said in Fifth Elephant that there are no Igorinas. Their daughters are pretty and quite normal.

Igorina was pretty, and did look normal, up until she made an effort to look abnormal.

Yes, I know. But they also have other names, I gathered. Igor is for the limping servents.
